The capital letter "J" would be above & below the line. I believe it is a "T" & it's Tom. I myself make a similar capital "T" & for an "F" which I use more frequently, cause my husband's name is Fred, I put a line thru the vertical stem. So I believe it's Tom Cox.

Okay I can now see why you think the last letter could be a 'p', but that first letter of the given name looks like one of my fancy capital I's.I do my own fancy writing on FRAKTUR documents. Trying to copy my own great grandfather's writing style, probably the Palmer method.
